Although it is totally personal impression, I think that the genuine toner cartridge is the best, after all. Although it does not deny the refillable compatible toner cartridge, considering the printing quality, the life, the price, the frequency of refilling, ..., etc., it seems that the genuine toner cartridges are going to rise. I think that it will be several ten repeats, but I will certainly buy the same genuine toner cartridge next.
